Just as Janice, I have donwloaded five times the same installer file for PRO, shown as being 5.7Mb large but actually being 4.7Mb, and causing no difference at all after uninstalling and reinstalling: the unapparent "PRO" version keeps on inviting me to "upgrade" to PRO for USD 18.00 I've already paid.

Is the link, pointing to the wrong installer file?

No useful feeback from the support page.

Thank you in advance for any guidance.
